Trail Overview

Branching eastward directly off FS 5830130, FS 5830140 is an out-and-back woodland spur that leads directly into the expansive Sink Quarry pit. Managed by the Mt. Hood National Forest, the corridor cuts through a lush, dense stand of mature Douglas firs and hemlocks before emerging into a broad, sunlit gravel bowl. The trail surface consists of an established, single-lane crushed rock and packed dirt track holding a difficulty rating of 1. Outdoor enthusiasts use this short spur to reach the open quarry grounds, which provide ample flat ground for dispersed camping setups, recreational target shooting, and scenic forest respites. Remnants in the gravel clearing also point to historical and recent tactical use as a forest fire helicopter landing zone during regional wildland fire operations.
